an extended star is a tree which has only one vertex with degree larger than two. the -center problem in a graph  asks to find a subset  of the vertices of  of cardinality  such that the maximum weighted distances from  to all vertices is minimized. in this paper we consider the -center problem on the unweighted extended stars, and present some properties to find solution.

the objective of the present study was to compare the efficacy of conventional and extendedintramammary (imm) therapy of persistent subclinical mastitis in lactating dairy cattle using nafcillinpenicillin-dihydrostreptomycin combination (npd). sixty-five dairy cows with 126 infected quarters were enrolled in the study. infected cows were allocated randomly to 1 of 3 different treatment regimens...

We question two of the basic foundations of the Extended Mind hypothesis originally formulated by Clark and Chalmers, i.e. that all cognition is organism centered and that the important theoretical issues that the debate surrounding the Extended Mind hypothesis can fruitfully be resolved by to a large extent rely on invented examples of cognitive activities as the empirical foundation. We sugge...

The paper will discuss the extended mind thesis with a view to the notions of “agent” and of “mind”, while helping to clarify the relation between “embodiment” and the “extended mind”. I will suggest that the extended mind thesis constitutes a reductio ad absurdum of the notion of ‘mind’; the consequence of the extended mind debate should be to drop the notion of the mind altogether – rather th...

This  paper extends the notion of fuzzy $BCK$-subalgebras to fuzzy hyper $BCK$-subalgebras and defines an extended fuzzy $BCK$-subalgebras. This study  considers  a type of fuzzy hyper  $BCK$-ideals  in this  hyperstructure  and  describes   the  relationship  between hyper  $BCK$-ideals and  fuzzy hyper  $BCK$-ideals.  In fact, it tries to introduce   a  strongly  regular  relation  on hyper $...

We develop complementary connections between McLuhan’s media ecology notion of media as ‘extensions of man’ and the Extended Mind Thesis of Andy Clark.

in this research complexation of dioxovanadium(v) with nitrilotriacetic acid (nta) at differentionic strengths (0.1 to 1.0 mol dm-3) of sodium perchlorate as supporting electrolyte and ph rangeof 1.00-2.50 at 25 °c has been investigated by a combination of potentiometric and uvspectrophotometric measurements. stability constants of two species, v0211l- and vo2h2l havebeen calculated. ionic stre...

this study describes the design, construction and calibration of an adjustable three-point hitch dynamometer. the dynamometer frame design was based on an inverted u-shaped frame that was mounted between the tractor links and implement. the dynamometer frame design allows for use in both category i and ii three-point hitch systems because of its flexibility in a lower point hitch spread and mas...
